In the very recent past, there was another post addressing this issue. I think there was a reply by Bobbi or Kimberly, can’t remember which one. Look for RAI in the search panel, and scroll through posts in the past week. If I see it, I will write to you again, tell you which one it was.
In your case, I think it matters a lot on what you were told. Or have you been told anything on this subject? But, as I reaall from other posts, yes, sometimes steroids are given before RAI, especially with TED signs.
